VOLTAIC ISNNER SOLE.

SPECIPICATIQN forming part of Letters Patent No. 371,189, dated October 11, 1887.

Application filed April '7, 1887. Serial No. 233,965. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE A. FULLER- TON, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Voltaio Inner Soles, of which the following is a specification, reference being had to the accompanying drawings, in which my invention is shown embodied in an insole, and in which- Figure 1 is a plan of an inner sole embodying my invention. Fig. 2 is a sectional view on line 2 2 of Fig. 1, and Fig. 3 is a sectional detail.

The so-called voltaic armor heretofore constructed has frequently been found defective or objectionable by reason of the form and arrangement of its electrical elements; and my invention consists in the combination of a backing with one or more rings of one kind of metal and one or more rings of another kind of metal, the rings being lapped and threaded by a strip which holds the rings in place and to the backing.

In the drawings, which show my invention embodied in an inner sole, A is the backing, to which the rings B, of one kind of metalsay copper-and rings D, of another kind of metal-say zincare secured by a strip, E, which threads the lapping rings and is made fast at its ends to the backing.

I ordinarily secure the end rings of a se-. ries to the backing A by fastenings a; but this is not essential, as the ends of strip E are readily secured to the backing so as to hold the rings in place. The rings B and D are preferably made of thin sheet metal, especially where flexibility is desired in the armor.

It will be observed that the lapping portions of the rings rub against each other when my armor is in use, and that the surfaces in cont-act are thereby kept clean and bright, so that the acidulous perspiration from the body acts the more readily upon the metals and strengthens the current of electricity set up by the contact of the dissimilar metals of which rings B and D are made, as will be plain to all persons skilled in the art.

While I have shown my invention embodied in an inner sole, it is clear, nevertheless, that it may be embodied in various other articles.

What I claim is In combination, backing A, one or more rings, B, of one kind of metal, and one or more rings, D, of another kind of metal, the rings being lapped and threaded by a strip, E, substantially as and for the purpose set forth.

GEO. A. FULLERTON.
